新型墙体材料专用砌筑水泥保水率试验方法研究

摘要

The masonry cement for new wall materials have excellent water holding capacity, using " Masonry cement " (GB/T 3183-2003)usual get higher retention rate value. By comparing the water holding capacity test of " Masonry cement " (GB/T 3183-2003) and " Ready-mixed mortar " (JG/T230-2007) , conclude that the method in " Ready-mixed mortar " (JG/T 230-2007) is more situable,and the retention rate value should not less than 95%.%新型墙体材料专用砌筑水泥保水性能很好,采用现有GB/T 3183-2003《砌筑水泥》标准测定的保水率很高.通过与JG/T 230-2007《预拌砂浆》中保水性能实验方法的对比,确认JG/T 230-2007《预拌砂浆》中的保水性能实验方法较适用于测定新型墙体材料专用砌筑水泥的保水性能,其值以不低于95％为宜.
